X9319WS8Z

Digital Potentiometers Overview

The X9319WS8Z is a single-channel digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics. It features a total resistance of 10 kOhms with a linear taper and 100 tap positions for precise adjustment. The device utilizes non-volatile memory to retain the wiper setting upon power loss. It operates on a single 5V supply voltage, with a specified operating range of 4.5V to 5.5V. The component is housed in an 8-pin SOIC surface-mount package and supports a serial interface for control.

Digital Potentiometers Procurement Notes

Verify current availability status as distribution channels may list this component as End-of-Life or obsolete. Confirm RoHS compliance details through official Renesas documentation before procurement. Check for alternate manufacturing site notices that may affect packaging or labeling specifications.

Digital Potentiometers Selection Notes

Select this component when non-volatile storage of the resistance setting is required without external battery backup. Ensure the design accommodates the 100-step resolution and linear response curve. Verify that the 5V logic levels are compatible with the controlling microcontroller or interface circuitry.

Digital Potentiometers Part Context

This part belongs to the X9319 series of Digitally Controlled Potentiometers from Renesas/Intersil. It shares functional similarities with other members like the X9317 and X9318 but differs in specific interface protocols and package options within the family.

Digital Potentiometers Replacement Considerations

Consult the official Renesas cross-reference guide for verified pin-compatible alternatives. Generic digital potentiometers may not support the same non-volatile memory retention or interface protocol.
